Constraints on the Origin of the Martian Dichotomy From Southern Highlands Marsquakes
Abstract The Martian hemispheric dichotomy is delineated by significant differences in elevation and crustal thickness between the Northern Lowlands and Southern Highlands. Yet, its origin remains controversial. Here, we improve the signal‐to‐noise ratios and determine the locations of the low‐frequency marsquakes recorded during the InSight mission ...

The mosaics of Mars: As seen by the Viking Lander cameras [PDF]
The mosaics and derivative products produced from many individual high resolution images acquired by the Viking Lander Camera Systems are described: A morning and afternoon mosaic for both cameras at the Lander 1 Chryse Planitia site, and a morning, noon,

Abstract Subsurface ice in the mid‐latitude regions is a significant water inventory on present‐day Mars, and their volume and distribution are thought to have varied due to the orbitally induced paleoclimatic changes. Using high‐resolution satellite images, the present study explores the distributions of three presumed periglacial landforms (thermal ...

Evolution of Water Reservoirs on Mars: Constraints from Hydrogen Isotopes in Martian Meteorites
Martian surface morphology implies that Mars was once warm enough to maintain persistent liquid water on its surface. While the high D/H ratios (~6 times the Earth's ocean water) of the current martian atmosphere suggest that significant water has been ...

The First Global Catalog of Rockfall Locations on Mars
Abstract Rockfalls are ubiquitous expressions of present‐day landscape evolution across the solar system. On Mars, their distribution has been proposed to indicate endo‐ and exogenic drivers, such as tectonic activity and solar‐driven thermal fatigue. Here, we present the first global catalog of 1,383 rockfall‐bearing locations on Mars, derived using ...

Revision of the Martian relative age chronology [PDF]
This study has provided a more detailed chronology than currently exists in the literature and has created some changes to the currently accepted geological evolutionary sequence of Mars.

Abstract The Thermal Evolved Gas Analyzer (TEGA) analysis of surface and icy subsurface Phoenix landing site soils consisted of low (300–700°C) and high (>700°C) temperature CO2 evolutions that were attributed to organic carbon (83–1,484 μgC/g) and Ca‐rich carbonate (1.1–2.6 wt.%).

Viking Lander 1 and 2 revisited: The characterisation and detection of Martian dust devils [PDF]
Dust devil data from Mars is limited by a lack of data relating to diurnal dust devil behaviour.
